Now that all of the software has been installed, it's time to reboot the computer. Before we reboot, let's unmount $LFS/proc and the LFS partition itself by running: umount $LFS/proc umount $LFS If you decided to create multiple partitions, you need to umount the other partitions before you umount $LFS, like this: umount $LFS/proc umount $LFS/usr umount $LFS/home umount $LFS And you can reboot your system by running something like: /sbin/shutdown -r now At the Grub menu make sure that you tell it to boot lfs and not the default entry which will boot your host system again. After you have rebooted, your LFS system is ready for use and you can start adding your own software.
